Wile on Vacation this year I took a train trip to Texas. In the Dallas Fort Worth area I noticed that on some buildings that the service drop conductors were eather white or gray in color phase and neutral. I thought this was odd to have white or gray conductors. I also saw this arangement on some residential services. My question is why the white or gray conductors? Was this some experiment with new insulation ? Inquiring minds want to know. THANKS HYPRESS
